Disco Abrasive Systems DAD-2H/6T

The Disco Abrasive Systems DAD-2H/6T is an automatic dicing saw for precision cutting, grooving, and slotting of semiconductor wafers and advanced materials. Engineered for high-accuracy R&D and production environments, the system delivers programmable cutting parameters, multi-axis servo control, and motorized workpiece positioning. A 1250 W air bearing spindle operating at 15,000 to 40,000 rpm provides cutting power across wafer sizes up to 160.4 mm diameter. The machine accommodates blade sizes to 76.2 mm and supports four preset cutting modes plus custom program storage.
